Abstrak

ABSTRACT
Effect of Organic Fertilizers on C-organic, total-N soil and Yield of Upland Rice (Oryza sativa L.) on
Ultisols Collected from Kentrong Area, Banten Province
This experiment was aimed to study the effect of various kinds and dosages of organic fertilizers on
C-organic, total-N soil and yield of upland rice (Oryza sativa L.) in Ultisols collected from Kentrong
area, Banten Province. The experiment was arranged in a randomized block design with ten
treatments and three replications. The treatments were control (without organic ferlitizer), poultry
manure 37.5 g/polibag, poultry manure 75 g/polybag, poultry manure 112.5 g/polybag,
vermicomposting 37.5 g/polybag, vermicomposting 75 g/polybag, vermicomposting 112.5
g/polybag, compost of straw 37.5 g/polybag, compost of straw 75 g/polybag and compost of straw
112.5 g/polybag. The result showed that there was an effect of various kinds and dosages of organik
fertilizers on C-Organic, but there was no effect on N-Uptake. For the yield of upland rice, dosage
of 112.5 g/polybag of poultry manure gave the best result which was 21.08 g/polybag.

ABSTRAK
Percobaan ini dilakukan untuk mengetahui pengaruh pemberian macam dan dosis pupuk organik
terhadap C-organik, N-total dan hasil padi gogo (Oryza sativa L.) pada Ultisols asal Desa Kentrong,
Provinsi Banten. Metode percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK),
dengan sepuluh perlakuan dan diulang tiga kali. Sepuluh taraf tersebut terdiri dari perlakuan
kontrol (tanpa pupuk organik), pupuk kandang ayam 37,5 g/polibeg, pupuk kandang ayam 75
g/polibeg, pupuk kandang ayam 112,5 g/polibeg, pupuk kascing 37,5 g/polibeg, pupuk kascing 75
g/polibeg, pupuk kascing 112,5 g/polibeg, pupuk kompos jerami 37,5 g/polibeg, pupuk kompos
jerami 75 g/polibeg, dan pupuk kompos jerami 112,5 g/polibeg. Hasil percobaan menunjukkan
terdapat pengaruh pemberian macam dan dosis pupuk organik terhadap C-Organik tanah tetapi
tidak berpengaruh terhadap N-Total. Untuk hasil panen padi gogo, dosis 112,5 g/polibeg pupuk
kandang ayam memberikan hasil panen padi gogo terbaik yaitu 21,08 g/polibeg.
